Brian, a middle-aged Canadian tourist on his first visit to San Jose Costa Rica, finds a red taxi outside the Hotel Del Rey and asks to be taken to Idem, a brothel he read about on the internet. He has to explain to the driver that it is located near the Tin Jo Chinese restaurant in the Barrio Chinese section. He finds it across the street, goes in, orders a cold beer at the bar and talks to the manager, named Roberto. He requests Roberto to send him a friendly chica. The manager, Roberto, asks him to be seated and sends over a young chica to talk to him. They sit and talk, frolic a little, giggle a bit, drink an Imperial, and she sits on his lap. He whispers in her ear and she gasps and runs away!
Seeing this, the manager, Roberto, sends over a more experienced chica to entertain the gentleman. They sit and talk, frolic a little, giggle a bit, drink some booze, and she sits on his lap. He whispers in her ear, and she too screams, "No!" and walks quickly away back to her seat at the wall.
The manager is surprised that this ordinary looking man has asked for something so outrageous that the two chicas will have nothing to do with him. He decides that only his most experienced lady, Maria, will do. Maria has never said no, and it's not likely anything would surprise her. So the manager sends her over to Brian. The sit and talk, frolic a little, giggle a bit, drink a bit, and she sits on his lap. He whispers in her ear and she screams, "NO WAY, JOSE!" and smacks him as hard as she can and leaves.
The manager, Roberto, is by now absolutely intrigued, having seen nothing like this in all his years of managing a brothel. He's sure he has the chicas say yes to everything a man could possibly ask for, including repeat customers named Ace, La Muerte and Don Gordo. He just has to find out what this man wants that has made his chicas so angry. So he goes over to Brian and says that he's sent him the best chicas in Idem that are available. He talks with him and asks him what is the problem.
Brian leans forwards and says, "Can I pay in Canadian currency?"

Funny!

It reminds me of the homeless man in downtown Seattle who was begging for money with a sign that asked for any spare change, but NO CANADIAN COINS.
